1. What is the main characteristic of cystic fibrosis?

• A. Multiple upper respiratory infections
• B. An underproduction of exocrine glands
• C. Excessive, thick mucus
• D. An overproduction of thin mucus

Correct answer: C

Rationale: The main characteristic of cystic fibrosis is the production of excessive, thick mucus. This thick mucus leads to blockages in the airways, digestive system, and other organs. Choice A is incorrect because while individuals with cystic fibrosis are more prone to respiratory infections, the main characteristic is the mucus production. Choice B is incorrect as cystic fibrosis is characterized by the overproduction, not underproduction, of exocrine glands. Choice D is also incorrect as the mucus produced in cystic fibrosis is thick, not thin.

2. A client with cirrhosis is receiving lactulose. What is the desired effect of this medication?

• A. Decrease blood glucose levels
• B. Reduce serum ammonia levels
• C. Increase platelet count
• D. Lower serum bilirubin levels

Correct answer: B

Rationale: The correct answer is B: Reduce serum ammonia levels. Lactulose is used to reduce serum ammonia levels in clients with cirrhosis, helping to prevent hepatic encephalopathy. Lactulose works by acidifying the colon, trapping ammonia for excretion. Decreasing blood glucose levels (choice A) is not the primary effect of lactulose. Increasing platelet count (choice C) and lowering serum bilirubin levels (choice D) are not direct effects of lactulose in the management of cirrhosis.

3. A client with chronic heart failure is being discharged with a new prescription for furosemide. Which instruction should the nurse include in the discharge teaching?

• A. Increase your intake of potassium-rich foods.
• B. Restrict your fluid intake to 1 liter per day.
• C. Avoid salt substitutes containing potassium.
• D. Weigh yourself once a week.

Correct answer: A

Rationale: The correct answer is to instruct the client to increase their intake of potassium-rich foods. Furosemide is a loop diuretic that can lead to potassium loss due to increased urinary excretion. Potassium-rich foods can help prevent hypokalemia, a potential side effect of furosemide. Restricting fluid intake (choice B) may not be suitable for all patients with heart failure, and a general restriction of 1 liter per day is not typically recommended. Avoiding salt substitutes containing potassium (choice C) is not a priority teaching point in this scenario. Weighing oneself once a week (choice D) is important for monitoring fluid status, but increasing potassium-rich foods is more directly related to the potential side effects of furosemide.

4. A child has developed a diaper rash, and the parents are using zinc oxide to treat it. What does the nurse suggest to aid in the removal of the zinc oxide?

• A. Mild soap and water
• B. A cotton ball
• C. Mineral oil
• D. Alcohol swabs

Correct answer: C

Rationale: To completely remove ointment, especially zinc oxide, mineral oil should be used. Mineral oil helps in gently breaking down and lifting the ointment without causing irritation. Mild soap and water (Choice A) may not be effective in completely removing zinc oxide. A cotton ball (Choice B) may not provide the necessary lubrication to aid in the removal process. Alcohol swabs (Choice D) can be harsh on the skin and are not recommended for this purpose.

5. Before selecting which medication to administer, which action should the nurse implement if a postoperative client reports incisional pain and has two prescriptions for PRN analgesia?

• A. Compare the client’s pain scale rating with the prescribed dosing.
• B. Determine which prescription will have the quickest onset of action.
• C. Ask the client to choose which medication is needed for the pain.
• D. Document the client’s report of pain in the electronic medical record.

Correct answer: A

Rationale: When a postoperative client reports incisional pain and has two prescriptions for PRN analgesia, the nurse should first compare the client’s pain scale rating with the prescribed dosing. This action ensures that the client receives the appropriate medication based on their pain level. Determining the onset of action or asking the client to choose the medication does not guarantee that the right medication is administered according to the pain intensity. Documenting the pain report is important but should not be the first action when deciding which medication to administer.
